A 7- FORM/EV- Patented Jan. 10, 1933 HENRY FRANCIS HARDY, F OTTAWA, ONTARIO, CANADA SLEEPING BAG AND THE LIKE Application filed April 21, 1930, Serial No. 445,918, and in panacla April 17, 1930.

This invention relates to sleeping bags, sleeping robes and like commodities and in particular has reference to the casing containing the filler material employed for such purposes.

Heretofo-re in the art of manufacture of sleeping bags, the filler casing, composed of cotton or a like material, has been formed in-a series of longitudinal tube like independent sections. One end of the sections during manufacture, being closed and the other end left open for filling purposes. The filling material .employed and commonly used, known as down, was then blown into the end of the tube like sections andafter a suflicient quantity has been blown thereinto, the open ends were then sealed by stitching and the article was then subjected to a beating by hand or otherwise, so as to distribute the down or filler material evenly throughout the length of the tube like sections.

After an article such as I have described had been in use for a period of time, the fil1- ing material gradually became displaced, moving in either direction, sometimes to one end and sometimes to the other and as a result of this, the filling material became .unevenly spread and invariably gathered in bulky formation in the corners of one end or the other, so that the article itself became objectionable, uncomfortable and impractical and did not effectively serve its purose.

p Inorder to obviate this unsatisfactory condition and to materially improve the qualities of sleeping bags, sleeping robes and articles of like nature, I have provided means for arresting the movement ofthe filler material within the casings so that even after extensive use the article will still retain its evenness of filler material and practicalness of purpose.

One of the primary objects of the invention therefore,is to effectively maintain an even distribution of filler material within the filler casing or housing.

A further obj ectof the invention is to provide a device of this nature which may be manufactured Without materially increasing the cost of the casing.

A still further object of the invention is to provide an article of this character wherein movement ofthe filler material from one portion to another of the casing is arrested, en.- abling the article to more satisfactorily and usefully perform the functions required of it.

Having regard to the foregoing and other objects which will become obvious as the description proceeds, the invention consists in the novel combination and arrangement of parts hereinafter described in detail and illustrated in the accompanying drawing.

Figure l is a fragmentary sectional perspective view illustrating my improved device embodied in a sleeping bag of single tube formation.

Figure 2 is a fragmentary view showing my improved device embodied in a sleeping bag constructed of staggered tube formation.

Figure 3 is a plan view of a modification which illustrates the baffle members in stag gered formation within the tube like sections.

Figure 4 is an enlarged sectional detail taken transversely of the sleeping bagillustrated in Fig. 2,-and indicating a baflle 0r flap member within oneof the staggered sections.

Figure 5 is a longitudinal sectional detail showing the baiflle members within the tube like sections in reverse or opposed relation with the filler material removed, and,

Figure 6 is a further longitudinal sectional detail illustrating the bafile members or flaps in opposed and staggered relation.

In the present invention wherein my improved deviceis embodied, Ihave indicateda casing or filler case by the character A and the baffle members or flaps by the character 13.

In the ordinary course of construction the member A is divided into a series of longitudinal tube like sections 10 by means of stitchings 11, one end of the sections, prior to being filled by down or the like C, is closed by the cross stitchings 12.

Any suitable or convenient means may be employed in securing the members B within the tube like sections of the filler case. However, I prefer to embody the baffle or flap members in the tube like sections during the manufacture of the filler case. For this purpose therefore, the members B, composed of strips of cotton or the like, are secured within the tube like sections and transversely thereof by means of cross stitching 13 while the sides of the baffle member are held by the stitchings 11 previously referred to. This particular form of stitching secures three sides of each of the baffle members within the tube like sections and enables the loose portions or fiaps 14 to act as baffle members.

Different positionings of the baffle members may be conveniently embodied in my invention. For example in Figures 1 and 2, I have indicated the bafile members as formed from transverse strips extending throughout the width of the filler case A and secured therewithin by the cross stitching 13 which is combined with the longitudinal section forming stitching 11. Other positionings of the baffle members are disclosed in Figures 3, 5 and 6.

In Figure 2 wherein I have indicated the filler case as being composed of a series of tube like sections arranged in staggered relation to one another, a separator or center section member 15 is employed as a securing means for the sections and this center section is mounted between the outer casing walls 17 and 18 respectively. Where the sections are in staggered relation, as illustrated, baffle members would of course be inserted in both the upper and lower sections.

In the modified form which I have illustrated in Figure 3, the bafile members are indicated in staggered relation to one another.

In Figure 5, which discloses an embodiment of my invention, the baffle members are arranged in reverse or opposed relation to one another.

In Figure 6 I have shown the baffle members as being arranged in opposed and staggered relation. It will also be understood that the free end 14 of the baffle members may be tacked at its center to the adjoining side of the section. This will enable the flap to increase its baffle effect.

In manufacturing my improved device, after the casing has been completed except for open ends, and the baffle members inserted in their respective positions transversely of the tube like sections and in spaced relation, filler material is blown thereinto in a well known manner and the open ends thereof sealed by stitching.

WVith the completion of the sealin the filler case is then subjected to beating fbr the purpose of equally distributing the down throughout the length of the tube like sections. This beating will cause equal distribution of the down throughout the various sections. As the down is being distributed it will engage the baffle members and be effectively obstructed and thus movement of the down or filler within the filler case is arrested and even though the complete article is used extensively the baflie members will arrest further movement of the down within the sections and thereby enable the filler case to preserve its original qualities of equally distributed filler material.

From the foregoing it will be readily observed that I have materially improved the qualities incorporated in a device of this character. Each tube like section forming a part of the sleeping robe or blanket, being provided with a plurality of baffle members which will arrest movement of the filler material therein. This, as is obvious, enables the device to preserve its uniformity of thickness and thus in a more practical and useful manner perform the functions required of it.

As many changes could be made in the above construction, and. many apparently widely different embodiments of this invention could be made without departing from the spirit or scope thereof, it is intended that all matter contained in the above description and shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

What'I claim as my invention is 1. A new article of manufacture comprising a casing formed with upper and lower walls joined together by spaced substantially parallel rows of stitching to form a plurality of elongated compartments, and bafiie members arranged in said compartments, each of said bafile members comprising a substantially rectangular fabric section'having opposite side edges secured to said wall members at opposite sides of said compartments by the rows of stitching joining said walls and secured along one end edge to one of said walls by a transverse row of stitching.

2. A new article of manufacture comprising upper and lower walls secured together at spaced intervals along parallel lines to define a plurality of elongated compartments,

a substantially rectangular fabric section within each of said compartments extending from side to side thereof and each secured along two opposite sides thereof to both of said walls and along one side to one of said walls to define therewith pockets opening in the direction of elongation of said compartments.

3. A new article of manufacture comprising a casing formed with upper and lower walls joined together by spaced substantially parallel rows of stitching to form a plurality of elongated compartments and fabric strips extending transversely of said rows of stitching between said walls and secured to the latter at spaced intervals by said rows of stitching, said fabric strips being secured along one transverse edge to one of said walls between said lines of stitching to provide baifles in said compartments.

In witness whereof I have hereunto set my hand.

HENRY FRANCIS HARDY.
